Hello,
I have a problem with 56F84789. When I debugged a programme, the Alert window showed up, as shown in Picture 1 below.Then I clicked on the "Yes" button, the programming failed and the console show the errors in Pricture 2.
I hope to get the help from you soon.
Have a great day!
Hi, SaiDe,
Do you use CW tools or flash programmer tools?
This is the security procedure, after Reset, the address P:0x40c is copied to FTFL_FSEC register automatically, only when the SEC bits is 2b'10 can the chip is in unsecurity mode. When you execute "mass erase" instruction, all flash including 0x40C are 0xFFFF, but the MC56F84789 is still in Unsecurity mode, after power on reset, the 0xff is copied to FTFL_FSEC, the chip is in security mode.
can you tell the background of the error?

Hi,xiangjun
I use CW tools. It may be caused by my misoperation. It worked normally,but I connected the JTAG incorrectly once, then the problem happened.
I need to get the chip normally. I want to know what should I do.
Have a great day!
Hi, SaiDe,
It seems that you can new a project and use the following option to mass erase the flash with Codewarrior for mcu ver10.7.
Hope it can help you
